DIY Super-Strong Sandpaper

I do a lot of finish-sanding freehand and the finer grits are usually bonded to thinner paper so learn how to make this super-strong sandpaper.

How to Make Durable Sandpaper

“I do a lot of finish-sanding freehand, without a sandpaper block, so I can smooth edges and get into nooks and crannies. But the finer grits are usually bonded to thinner paper and, at least for me, the paper is too thin and ends up tearing long before the grit wears out. So I apply duct tape to the back of the sandpaper. The sandpaper is still flexible enough to sand a tight radius and it’s far more durable. You can use this super-strong sandpaper like a shoeshine rag.” — Chuck Merchant
